Valoe Corporation disclosed in March 2022 that Valoe and Sono Motors GmbH moved to the industrialization of Solar Cell Assemblies for Sono Motors' Sion series-validation vehicles. Sion is Sono Motors' self-charging solar electric car. Valoe and Sono Motors have now signed a Contract on the final phases of having the solar cell assemblies for vehicle integration fully tested and ready for mass production.

This testing and acceptance phase is expected to be completed as soon as possible. The first testing phase is expected to be ready in September and the long-term testing procedures by mid-December 2022, at the latest. Upon successful completion of the agreed tasks, Sono Motors pays Valoe a success fee of total €1.0 million: €0.4 million for the phase one and €0.6 million for the phase two, to be completed in December.

Sono Motors intends to nominate Valoe as the supplier of solar cell assemblies for its Sion, manufactured by Valmet Automotive Oy.
